Our idea is to conceive an integrated end-of-pipe method for detoxifying effluent streams of dye factories. The goal is to achieve a two-stage regimen in sequence to ensure optimal conditions for the degradation of azo dyes within a batch bioreactor system. This would be an attractive and effective approach to dealing with azo dye contamination of the environment. As a financial incentive, we are also looking at maximizing the profitability of various potential breakdown products. As a lucrative continuous-process alternative, we are investigating the application of microbial fuel cell technology to an aerobic bioreactor system, for simultaneously detoxifying azo dyes and generating electricity.

                 <p>Depending on the azo dye that is being degraded, different sets of breakdown products can be produced. Once degraded, each of the different compounds will be identified and separated. We have three potential avenues for re-using these products: (1) converting functional groups on the aromatic amines into simple aromatic fragrances; (2) isolating and diverting nitrogenous compounds to algae, which can form, and maintain, a symbiotic relationship with the dye-degrading <em>E. coli</em> hosts; (3) selling more complex compounds to pharmaceutical companies for the production of drugs.
